Criminal justice client rehabs can be considered like a significantly better option than prison time or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, someone who has been found guilty of driving drunk of alcohol or drugs may be eligible for rehab services because of their problem as an alternative to serving time in jail. The judge could even order that the individual receive treatment, either alone or in addition to other sentencing. New offenders in particular tend to be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it is an option. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that do take part in rehab have a much better probability of remaining out of the system after rehab.
